former of which is provided with an arm 39 terminating in a fork 40engaging the clutch 28, while the rod 38 is provided with a similar arm41 having a fork 42 which engages the clutch 27.

As will be seen by referring to the drawings if the rod 37 is movedforwardly the clutch 28 will be moved into engagement with the (rear 24,locking the same upon the drive sha t, when the vehicle will be driventhrough the gears 22, 31, 33 and 24 forming the low gearing ofthetransmission mechanism. If the clutch 28 is then released and the rod 38moved rearwardly to bring the clutch 27 into engagementwith the gear 23,the drive will be through the gears 22, 31, 32 and 23, forming theintermediate gearing of the transmission mechanism. If, then, the clutch27-is moved out of engagement with the gear 23 and the rod 38 moved tob-ring the clutch 27 into engagement with the gear 22, the shafts 12 and15 will be locked together and the drive will be direct from the crankshaft or on the high gearing of the transmission mechanism. If the rod37 is moved rearwardly to bring the clutch 28 into engagelment. with thegear 25, the drive will be through the gears 22, 31, 34, 35 and 25,which is the reverse drive.

My present invention relates primarily to the mechanism by means ofwhich the clutchoperating rods 37 and 38 are reciprocated and thedescription ofthe mechanism above given has been introduced merely torender more clear the operation of my device.

As shown in the drawings, the top of thc transmission casing 17 is openand secured upon the top of this casing is a casing 43 which inclosesthe controlling mechanism proper.` Secured to the upper portion' of theinner face of the rear wall of this casing is apair of spaced brackets44 and 45 and centrally pivoted upon these brackets are cross bars 46and 47. Each of these cross bars is free to swing upon its pivotal pointandthey are connected to therods 37 and 38.1'espectively in such amanner that such swinging will be communicated to the rods toreciprocatethe same. I have illustrated in the drawings two separate and distinctmeans for connecting these bars to` their respective rods, one meansbeing shown in the connection between the bars 46 and the rod 37, whilethe other means is shown in the connectionbetween the bar 47 and the rod38. Bolted or otherwise secured to the cross bar 46 by one arm is aZ-shaped lever 48, the free arm of which-is bifurcated to form a fork49whieh engages in the groove 50 of a block 51 Carried by the rod 37.Pivotally secured by one end to one end of the cross bar 47 1s a link52, the other end of which is pivotedupon a trunnion 53 formed upon ablock 54 carried by thel rod 38. As will be seen, the turning of thecross bar 46 will act, through the lever 48, to reciprocate the rod 37while the turning of the cross bar 47 will act, .through the link 52, toreciprocate the rod 38, the direction of movement of the rod in eithercase depending upon the direction in I with a bevel gear 61 by means ofwhich the shaft may be revolved asA will be hereinafter explained. Theother endfof the shaft is Teduced to form a trunnion 62 which isjournaled in a socket formed in the end ofa bolt y 63 which is threadedinto a tapped bore formed in the opposite side of the casing.

= The portions of the shaft 59 beneath the push rods 55, 56, 57 and58arev notched as at 64, 65, 66 and 67. -As will be seen when one ofthese notches is directed upward, the corresponding push rod will tiltdown to scat in the notch and will, therefore, besupported at a lowerlevel than the remaining push rods. These notches are formed in theshaft in staggered relation and in suchv a man-ner that, in onepositionof the shaft, all of the push rods will 'be supported in raised positionand in such a manner that but one push rod at a time can be'lowered. Inorder to insure the proper seating of the push rods in the notches ofthe tumbling shaft 59, I have provided leaf `springs 68, 69, 70 and 7,1,which, as shown, bear upon the push rods intermediate their Alength andexert a constant downward pressure upon the'same,'th`e springs 68 and A69 being securedl to the pivotal point of the cross bar 46 by oneend-and' having their opposite ends bearing upon 4the push rods '55 and56 while the springs 70 and 71 are each secured by one end to thepivotal pointof the cross bar:v 47 and have their free ends bearing uponthe push rods 57 and 58. As shown, the free ends of these'springs :areenlarged and `provided with downwardly-extending llt) spacedpins72,'fwhichf bear oneupon each side of thepushro'ds and sopreventdisengagement of the springs. i

Extending longitudinally of the casing' is a pair of parallel, spacedguide rods 73,

Vwhich'are passed through sleeves 74 carried by the ends-of a cross head7 5, which is thus mounted for reciprocation longitudinally of thecasing.v The upper face of this cross head isV provided' withtransversely extending' grooves 76, 77, 78 and 79, in which the pushrods 55, 56, 57 and y58 restand which serve` tomaintain said'rods inproper spaced position softhatf` theyfiwill seat'fin thirl respective fnotehesoffv the vtumhling:fshaft` Eaehwof@ thei push rodsi'sforni'ed-with afshould'erf()*"eX-s tending `fdo'wnwardlyp` nom @itsylower' f face; zwhieh is slidaible' through. thevgroove ofi ithecrossthe'rd ff'when'" theitpusha rediris@y in i nominal@ position butvwhiehfwill engagewvith theierossi head when :the push- ?rod isiseateclin iits notch in the tumbling ishaift y595i thseI shoulders be"-`vllingfforrneel `atrav ipointibetwe'en the" erossfliead if i and"thefpivoted endsof .thev pushfrods".` Eaeh'zf pushz rodisi alsoI'Jroi'zided':Iup'on'r the@ otherside e of'- the Ierossuhea'd'Withaltransversely eXtend-= i ingipin i813? t-hei ends of"` `whicheXtencl/iuponi* J Aeach: side 'ofi the: pushlrodfinipositionto envvgag'efagainstfthe` 'cross hea'df i-wh'enj'theflatter f is drawnfltowerdthe' fronti end: off the easing-;

The clutch pedal 100is then released to throw in the clutch 14 and to move the cross headtoward the rear of the casing, during which movement it engages with theshoulder of the push rod 58, which, in the meantime, has fallen into thenotch of the tumbling shaft, forcing the same rearwardly and turning thecioss bar A17 to throw the transmission clutch 27 into engagement withthe gear 23, thus giving intermediate speed.

When desired, the high gear can be thrown in by moving the lever 112 tothe notch 117 and again operating the clutch pedal.

If, when the gears werel in neutral position, a reverse drive had beendesired, the lever 112 would be swung to the notch 118 and the clutchpedal actuated.

As will be readily seen, both the brake pedal 92 and the clutch pedal100 throw the clutch 14 into inoperative position, but the operation ofthe brake pedal in no way affects the gearing of the transmissionmechanism.

It is to be noted that, when the clutch pedal is actuated to throw inthemain clutch, the cross head will be actuated. and through the mechanismhereinbefore described will place a selected set of the transmissiongearing in position for operation. When the clutch pedal, however, isoperated to throw out the main clutch, it will move the cross head,`inthe opposite direction yand return such selected set of transmissiongearing and the connecytions therefor to neutral position, and thisreturning of such parts to neutral'position is accomplished irrespectiveof the position of the selector mechanism at such times, that is to saythe selector mechanism may be in selective position for any other of thesets of transmission gearing at the time a selected set is going toneutral position without interfering with `or prev-enting the return ofsuch selected set. to neutral position.

Further, it will be noted that, when the cross head is diawn toward thefront of the casing, it will, by contact with the-pins 81, move toneutral position any of the push rods which mayhappen to be out of suchneutral position. f

Another advantageous feature incident to my invention is thata certainset of gearing may be selected while the machine is running, and anotherset of gearing is in position, this selection taking place prior tochanging from one set to the other set of gearing and without affectingthe gearing in use. For instance, if the machine be traveling on aVlevel vroad with the high gearing in use and is approaching a hill orrough stretch of road where it is desired to use the low gearing, thequadrant lever may be movedto the low position at once ing to lowgearing.

vshiftable elements ratio.

to select such low gearing, but the latter, of

YVhen the hill is reached, it is only necessary for the operator toactuate the foot pedal as before described, to make the change from highgea-rv If, however, upon reaching the hill, the driver decides tecontinue `on `the high gearing, he may do soby failing to operate thefoot pedal, as themcre fact that he has selected the low gear byactuating the Vquadrant lever does not effect the operation of thetransmission mechanism unless thepedal itself be actuated. `Thus, itwill be seen that a desired set of gearing may be selected prior tochanging to the saine and while running upon another set -of gearing andwithout affecting the latter...

It will be apparent from the foregoing-de-` scription that I haveprovided va simple and eii'icient controlling lmechanism progressivetype adapted and arranged to of Vthe Y operate a transmission`Imechanism of the s-e-.r`

lective gear type without theaid of the ordinary change gear leverand Hgate, the operating mechanism consisting wholly of the clutch pedal andthe quadrant lever, which latter is se positioned that it maybe operatedwithout removing the hands from the steer-` ing wheel. f

It will furtherl'ie-seen that `the quadrant lever 112 may be moved toany position at any time without changing any gears in the transmissionmechanism until the clutch 14 is released and then thrown` in again.

The lever 12 and its connected parts comprising the tumbling shaft 59constitute what maybe termed a universal selector,` since it is freelymovable atl all times and it may be operated to select` asubsequentspeed ratio of the transmission mechanismwhether the mainclutch is engaged or disengaged and whether either ofthe shiftableelements of the transmission -mechanism is in its opei'ative position orboth elements occupy their neutral positions. It is to be understoodthat the term universal selector mechanism employed herein refers toselecting mechanism that may be adjusted at any time and iricspective ofthe ypositions ofthe clutch and the to select a subsequentspeed If thelever 112, is actuated to one ofthe I speed positions otherthan that inwhich the transmission' mechanism is operating', at any time during-theforward movement ofthe clutch pedal, that is,.during the 'disengage-`ment ol"` the clutch *and the returning ofaI shiftedfelement toitsfne'utral positioinfthe position of the lever will determine thespeed ratio secured by the return movement of the clutch pedal. Thisresult will be secured regardless of the fact that another speed ratiohad been selected before the actuation ofthe clutch pedal.v v

' shiftimay be completed,ifdesircd. c Itis then necessary to return the`cross head to its extreme left-hand position, as viewed in Fig. 2, tobe in position to engage the shoulder of the rod corresponding to theselected speed ratio.

It will also be seen that the clutch is always released before any ofthetransmission gears are shifted and that the gears are always inposition before the clutch is again thrown in.

It Will, of course, be understood that minor changes in the details ofconstruction may be made if desired Without in the slightest degreedeparting from the spirit of my invention, which', broadly speaking,consists of a f control mechanism for a selective gear .transmissionmechanism operated and governed by a singlelever and the clutch pedal.
